STORAGE BATTERY.

Specification of Letters latent.

To all whom it may concern:

Be it known that I, LOUIS H. FLANDERS, a citizen of the United States, and a resident of iVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Storage Batteries, of which the following is a specification.

My invention relates to secondary or storage batteries, and more particularly to means for joining the plates of a cell having the same polarity and for connecting the plates.

of one cell to those of another, and it has for its object to provide simp1e,convenient" and efficient means for this purpose.

In order to minimize the cost and to fa cilitate the manufacture and repair of secondary or storage batteries, it is exceedin ly-1 important that simple means be provided or joining plates of like polarity and for connecting groups of one-cell with the proper groups of others. Heretofore, the labor and expense incident to the removing of one or more cells from a battery for the purpdse of cleaning or repairing, or for other reasons, have been excessive, and the operation of re-connecting the cells in the batteries has been a diflicult one, owing to the fact that the connecting means have generally been complicated or difiicult of application.

My invention is illustrated in the accompanying drawing, in which Figure l is a .view, in perspective, of the upper portions of two cells of a secondary battery to which my invention is applied. Fig. 2 is a view, partially in elevation and partially in section, of the connecting means comprising my invention, and Fig. 3 is a plan view of two connectors joined together,

Each of the cells 1 and 2 comprises groups of electrodes or plates 3 having lugs 4 which project from their upper ends. The plates of one polarity are so arranged in the cases 5 that their 'projecting'lugs are all locatedat one side, and, the plates of opposite polarity are so arranged that their lugs are all located at the opposite side of the cases.

A connecting plate 6 has countersunk apertures 7 so spaced andof such dlmensions that when applied to the cell the lugs 4 just 'fit into the apertures and project through them. By means of a blow-pipe, the portions of the lugs which project through the apertures may be burned or melted until the lugs and the plate are securely united.

lead or a lead compound, the object of the copper core being to increase the strength and conductivity of the terminal connections between the cells and between the batteries .and the external circuit and to reduce-the for that purpose, which fits snugly about the abutting ends of the lugs 8, a blow-pipe flame and a small amount of extra lead, the lugs may be properly united.

It is not at all necessary to arrange the cells of a battery as shown in Fig. l, as may be understood by referring. to Fig. 3, in which only the connecting plates 6 and their lugs 8 are shown. The cells may be arranged side by side, end toend or in any other desired manner. If it is desired to disconnect a cell from the battery, it is only necessary to cut the connection between the two cells at the point where they were previously united, and if it is desired to return the cell Patented Oct. 19, 1909.

to the battery at a subsequent time, the ends of the lugs 8. may be united as before described, no more difficulty being experienced than when first united, and it is this feature which I claim as one of the special advantages of the connecting means constituting my present invention. It is to be understood that the lugs 8 may be utilized in the manner and for the purpose described,

either with or without cores of different mavariations may be provided with a core of greater conductivity and tensile strength than the surrounding material and adapted to be bent to the right, left or directly back for the purpose of an togenously connecting the surrounding material with the surrounding material of a similar lug of an adjacent cell.

2. In combination With the electrodes of a storage battery, a connecting plate autogenously connected to the electrodes of like polarity and provided with a flexible terminal lugformed integrally therewith and provided with a core of greater conductivity and tensile strength than the surrounding material and adapted to be bent in any direction for the purpose of autogenously connecting the surrounding material'With-the surrounding material of a similar lug of an adjacent cell.

3. In a storage battery cell, the combination with the electrodes of a plate autogenously connected to the electrodes of like polarity, a symmetrical terminal lug inte' grally formed with said plate and symmetrically located with reference to the sides of the cell so that it may be bent in any direction to be autogenously connected to Manila; 7,

terminal lug on the next adjacent cell.

4. In a storage battery cell, the combination with the electrodes of a plate autogenously connected to the electrodes of like polarity, a symmetrical terminal lug integrally formed with said plate and symmetrically located With reference to the sides of the cell so thatit may be bent in any direction to be connected to a similar terminal lug on
